    v1.1.20

    May 2024

    Container environment

    • [Collection] Fixes an issue where built-in collection jobs could not be overwritten by custom jobs.

    • [Collection] Adds the `aliyun_prometheus_agent_hpa_max_limit` self-monitoring metric for the maximum number of replicas.

    • [Collection] Improves support for running in VPC-hosted scenarios.

    • [Collection] Adds a feature switch to enable metric reporting over HTTPS.

    • [Collection] Adds support for adaptive metric collection in ASM mTLS environments.

    • [Collection] Fixes an issue where metric preview URLs failed because they contained invalid characters.

    • [Collection] Fixes an issue where the program did not work because the collection configuration loaded a local CA certificate that did not exist.

    • [Collection] Adds the push of self-monitoring metrics for regions such as Saudi Arabia.

    • [Collection] Adds node name labels to Node Exporter metrics in built-in collection jobs.

    • [Collection] Disables the registration capability of Prometheus storage instances.

    • [Collection] Supports metric convergence based on bucketing in multi-replica mode.

    • [Management] Provides an independent component for Prometheus instance registration. The registration mechanism for collection components is disabled by default.

    • [Management] Provides the ability to install and uninstall Integration Center components.

    • [Management] Adds support for enabling Container Monitoring Pro Edition.

    • [Kube-State-Metrics] Upgrades the AutoScaling API to v2.

    • [Kube-State-Metrics] Upgrades the CronJob and PodDisruptionBudget API versions to v1.

    • [Kube-State-Metrics] Adjusts security policies.

    Alibaba Cloud service

    • Provides more timely data processing. In large-scale data collection scenarios, the metric latency is reduced to seconds.

    • Metric collection starts in seconds instead of minutes for newly integrated Alibaba Cloud services.

    • Adds the ability to inject custom tags from Alibaba Cloud services into metrics.

    • Because of an architecture adjustment, self-monitoring metrics related to the Prometheus Agent are no longer delivered to user instances. These metrics are free of charge. If your alert rules depend on self-monitoring metrics for non-cloud services, such as metrics starting with `aliyun_arms`, remove the dependency before you upgrade.

    • The arms_instance_id and arms_instance_name metrics from some older instances are deprecated in this version.

    • Because of an architecture adjustment, querying the list of targets is no longer supported.

    Container environment

    • Improves the metric collection latency for newly connected large-scale clusters.

    • Optimizes the service discovery mode to reduce the impact of configuration changes in different collection jobs.

    Helm version

    Agent image version

    Description

    Release date

    Impact

    v1.1.18

    registry.{REGION}.aliyuncs.com/acs/arms-prometheus-agent:v4.0.0

    • Adjusts the request and limit of resources such as Node Exporter and GPU Exporter.

    • Adds support for configuring the Node Exporter port number. The default value remains 9100.

    December 2023

    This upgrade does not affect your business.

    v1.1.17

    registry.{REGION}.aliyuncs.com/acs/arms-prometheus-agent:v4.0.0

    • Adds a collection task for cluster events to support the Kubernetes deployment dashboard.

    • Adds instrumentation of self-monitoring metrics based on Service-Level Agreement (SLA) for the SLA stability dashboard.

    • Adds support for the BasicAuth authentication method for ServiceMonitor. The Secret must be in the same namespace as the ServiceMonitor.

    • Adds the Metrics Metadata feature to display the meaning of specific metrics.

    • Adds support for passing the Agent Chart version to the server. The server then initializes or upgrades the dashboard based on this version number.

    • Adds self-monitoring metrics for RemoteWrite to count the time consumed to send each data batch.

    • Adds self-monitoring metrics for errors and latency in basic metric collection.

    • Adds self-monitoring metrics for errors and latency in business metric collection.

    • Optimizes the default `queue_config` parameters for RemoteWrite to `min_shards=10`, `max_samples_per_send=5000`, and `capacity=10000` to improve adaptability for large-scale clusters.

    • Optimizes the service discovery method for CSI collection jobs, mainly for PV collection.

    • Optimizes the senderLoop distribution frequency and modifies the syncWorkersSeries frequency to reduce unnecessary disturbances.

    • Streamlines some logs and adds more detailed information about the time consumed by the scrape link to other logs.

    • Optimizes the collection period and timeout settings for basic metric collection jobs. These jobs are now configured separately and no longer use the global configuration. This reduces unnecessary interference with basic metric collection.

    • Optimizes the interaction logic in the multi-replica Master-Slave mode. Master and Worker nodes no longer affect each other, which improves stability.

    • Optimizes the Master node's target distribution policy. This saves about 30% of CPU and 40% of memory overhead and improves collection performance.

    • Optimizes metrics_relabel, reducing CPU usage by 70%.

    • Optimizes the Informer listener logic in multitenancy scenarios, saving about 20% of CPU overhead.

    • Optimizes the handling of occasional CoreDNS domain name resolution failures. The system automatically switches to and continues to use cached IP addresses. This reduces the dependency on real-time domain name resolution by CoreDNS and improves data sending stability.

    • Optimizes the logic for distributing collection configurations in SendConfig to improve distribution stability.

    • Optimizes the Master pre-scrape policy to save Master resource overhead and improve the Master's service discovery and target scheduling capabilities.

    • Optimizes the automatic rotation for single large packets that are greater than 1 MB. This reduces data packet loss caused by backend limitations.

    • Fixes an issue where some collection targets in ScrapeLoop could not be stopped, which caused repeated collection.

    • Fixes an issue in multitenancy scenarios where the label cache for pods was not updated promptly, which caused one timeline to become two.

    • Fixes an issue where the Master node occasionally failed to distribute targets for OOM or restarted replicas, which caused some collection targets to be lost.

    • Fixes issues with parsing Secret types and transmitting headers in RemoteWrite.

    • Fixes an issue where the shutdown operation for Kubernetes pods occasionally did not take effect.

    • Fixes an issue where the global default parameters and external_labels did not take effect. Custom modifications are now supported.
